众所周知,农药造成农田生态系统的不平衡,污染环境和危及人类健康。另外,害虫抗性品系的发展使作物保护面临新的困难。为此,人们正在努力寻找保护作物的新途径,例如害虫天敌的利用,虫生性病原体的利用,释放绝育雄虫以及昆虫生理活性物质的利用等。昆虫信息素是同种类个体间传递信息的化学物质,活性高,专一性强,对人畜无毒。它的分子结构一般较简单,便于合成,因此它在害虫防治中具有很大的潜在利用价值。一、昆虫信息素的一般性质昆虫信息素可分为释放型信息素和诱发型信息素。释放型信息素可立即引起受体的 It is well-known that pesticides cause the imbalance of farmland ecosystems, polluting the environment and endangering human health. In addition, the development of pest resistant lines is facing new difficulties in crop protection. To this end, people are trying to find new ways to protect crops, such as the use of natural enemies of pests, the utilization of pathogenic pathogens, the release of male sterile insects, and the use of insect physiologically active substances. Insect pheromone is the same kind of chemical substances passing information between individuals, high activity, specificity, non-toxic to humans and animals. Its molecular structure is generally simple, easy to synthesize, so it has great potential value in pest control. First, the general nature of insect pheromones Insect pheromones can be divided into release type pheromone and induced pheromones. Release pheromones can cause immediate receptor
